前に作ったBOX開発環境のインスタンス化

# BOXのインスタンス化する

[Rubyの開発環境を作った記録](http://qiita.com/MahoTakara/items/f48cdf29ddfd17f954bf)で作成した vagrant の BOX から開発環境を起動した時の記録です。

vagrant を起動するための ディレクトリを作成する

```
pxedhcp1:Vagrant maho$ mkdir RubyDev4
pxedhcp1:Vagrant maho$ cd RubyDev4
pxedhcp1:RubyDev4 maho$ ls -la
total 0
drwxr-xr-x   2 maho  staff   68  8 16 15:08 .
drwxr-xr-x  21 maho  staff  714  8 16 15:08 ..
```
ボックスのリストを確認する

```
pxedhcp1:RubyDev4 maho$ vagrant box list
RoRDev_Ubuntu14     (virtualbox, 0)
Ubuntu14.04_minimam (virtualbox, 0)

pxedhcp1:RubyDev4 maho$ vagrant init RoRDev_Ubuntu14
A `Vagrantfile` has been placed in this directory. You are now
ready to `vagrant up` your first virtual environment! Please read
the comments in the Vagrantfile as well as documentation on
`vagrantup.com` for more information on using Vagrant.
```
Vargrantfile を編集する。　編集内容は、メモリの２Gバイト化、CPU２個、プライベートLAN追加です。

```
pxedhcp1:RubyDev4 maho$ ls -la
total 8
drwxr-xr-x   3 maho  staff   102  8 16 15:09 .
drwxr-xr-x  21 maho  staff   714  8 16 15:08 ..
-rw-r--r--   1 maho  staff  3027  8 16 15:09 Vagrantfile
pxedhcp1:RubyDev4 maho$ vi Vagrantfile 
```
仮想マシンを起動する。

```
